I probably shouldn't post this, since I would rather buy next month...

but tenatively I'm looking for a few gears.

anybody have or know someone that has a:

3rd gear size: P

or a 4th/5th gear in size: T

thanks for the consideration

hey gear guru's
would either of these been original equiptment in some obscure 901 box, or are they both race ratio's only.

T and P.... guessing race only....

S is common.... Seen M/N/O but no P's in person.///

thanks Aaron..

perfect...
just what I was looking for.
it seems that 1968 was the year of the T

but it also looks like the P is a pipe dream.

back to the drawing board (or calculator)

I'm having a "bondo is out of money" sale on the stuff I have, no Ps or Ts tho. See classifieds for details. Remember that you can do some flipping to get ratios you want, but only when you mobe a 3rd to 4th or 5th, or a 4th or 5th to 3rd. (actually, you HAVE to flip them in those cases) For 4 speeds, that changes to 2nd to 3rd or4th, or 3rd or 4th to second.. the 4 speed is just a 5 speed with no first, so second becomes first, etc.

bondo...

I see..
why didn't I think of that first.
I understand flipping gears, but I didn't think of the obvious.

thank you.

so my mythical P gear is really a flipped X

yea!!!!! I have two X gears in my stash....

no I just have to find a 1968 911 t,e,or s that is parting out in order to find my T gear.

how does this group sound:
F/K-L/P/T/W

wooo- hooooo........!!!!!

And isn't F a little tall for 1st? That's the stock second gear. It works for V8s, but I don't think it'd be a good first gear for much else.

actually, i think it'd be a nifty gear for a vintage racer that sees airport circuits and doesn't have to deal with standing starts. make for 5 useable gears. your crew can help push you off the false grid...

K or L 2nd is plausible if you have a 904 mainshaft, of course...

K-L is just the ratio between what would be a K gear and an L gear.
Its what the letter assignment would be for a flipped ZD

so the box I'm putting together has a machined main shaft (ala 904) and I'm intending to run my flipped ZD in the 2nd gear slot

-------------------------------------------------

It will be a good first gear for the race track. We do rolling starts and the only time that 1st gear is ever used is in the pits. If I move F down into the 1st gear location, then that is kinda like having a 6 speed, because I get to have 4 more useable forward gears after F

alot of race cars look for hard to find C gears for 1st, but the F is better/more useable and cheap too

ooopppsss...

OK her goes this is my stash as of today.
these are the synchro'd gears letter # of teeth and stamped marking: A 29 IN3, T 29 IN3, V 31 IV, T 27 IV, 34 no other marks got two of them, B 34, T 34, S 27 IV, P 29,
non synchro gears T 23 IN3, X 23 IN, 25 no other marks.....
looks like both ring gears have 31 teeth pinions have 7 just an optical illusion as one ring gear is bevelled on the back side.

Need to build an Autocross box close 1234 and at least ZD 5th. I will sell the rest, most of the dog teeth have had it.

hmm...
I replied, but it must have hic upped.
lemme try again.

Joe, let me do some research and see how many teeth are on each half of the T gear (I mean the 2 seperate gears that combine to make a T)

Also, I can't remember which of the two pieces that the dogs are on for a 4th gear set, but I'll figure it out tonight.... and see if your willing to sell.

groot,
do you know if your O gear is for the 3rd gear space or for the 4th gear space. I think they make one of each and they don't interchange... See my above comment, I'll have to figure out which half of the set has the dog on it for a 3rd O versus a 4th O

thanks

Otto's has reasonable prices on "C" first gears.

Now for a 904 mainshaft & LSD and I'll be in biddness.....Otto's has them also....not sure bout the reasonable price bit tho.

I have an M and S, but if I sell them I'll figure out that I needed them, so I'll just hang on to 'em for now. I think that makes sense. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
